Be itknown that I, ROBERT GARVIE, of Hartnsefullmprovements in Clean-Outs for Drainage-Pipes, of which the following is a full, clear, and exact description, whereby any one The object of my invention is to provide means for getting ready access toa soil or; drainage pipe, such as is commonly-used in sanitary fittings in a building, without unsoldering the parts, and to this end my inventionconsists of a tubular body part in combination with a cover and cap, and in the details of the several parts making up the device particularly.-hereinafter described and pointed out in the claims.

Referring to the drawings: Figure, 1 is a' to a drainage pipe, with parts in section. Fig.

2 is a detail top view of the cleanout,'with parts broken away to show construction.

In'the accompanying drawings the letter a denotes a length of soil or drainage pipe, that joining piece, one of the branches I? looking upward, and in this upturned branch the body part c of the cleanout is secured, as by cementing or leadingin, the spigotend c of the cleanout fitting a bell mouth 11 of the branch. r The cleanout may be fitted in any desirable position to a pipe looking in any direction,

that is, it may fit' on top, bottom or side of any pipe joint or coupling part-having an adapting it to fit upon the different sizes of pipe ordinarily used in a building. The mouth c of the cleanout is flaring, and on the inner side a ground surfaced is provided.

upon which the edges of the cover e fit, the cover being ground to .place and forming a ground joint at f, the angle at which the joint tically air tight contact, being such as not to cause the cover to stick unduly in the socket. Directly back of the joint an upturned flange ,or'surface e is provided, and upon this the v underside ofthe cap 9 bears when .thelatter with a central stem 6? that projects outwardly througha hole in the center of the cap and forms a guide in screwing the latter to place. This stem extends through a hub g in the cover the edges of which are squared or properly shaped so as' toadap't them to be grasped by a wrench or keyused to remove or replace the cover. The cap is preferably of a size that enables it to fit completely over the end v and has a flange g that is threaded upon the inner side to fit upon the threaded exterior surface of the outer end of the body part of the cleanout.

It is obvious that any other means of securing the cap-t0 the cleanout may be. em-

parts as herein set forth as any means 0f-seployed without departing from my invention curing the cap to the body part ofthe cleanout may be employed and come within the scope of my invention.

In the operation of the device the body part of the cleanout having been secured to a pipe the cover is placed in the outer end and drawn to its seat by screwing on the cap, the stem (2 extending through a hole in the cap forming a guide that seats the cap as well as the cover and prevents any stripping of the thread.

When the cap is in place a certain portion of its under surface bearscontinuously all around upon that portion of the cover which lies directly opposite the joint soas to form .a firm seat.

The cover is preferably formed of the same material as the body partof the cleanout so that there is no chance for leakage of noxious gases or odors byany loosening of the joint by any unequal expansion and contraction of'parts, nor is it necessary to employ any packing device other than that comprised-in the partsthemselvcs.

The advantages of my device over those of the prior art are that by reason of the construction when the cap is secured in place with a portion of the cover projecting therethrough an absolute certainty of fit is assured of the cover in its seat thus avoiding the use' of packings and the preventing the escape of gases.

I claim as my invention--' v 1.- ha cleanout, in combination with the bodypart having an. interior flaring seat, a-

cover having a tapering edge, ground to the seat, and a central projecting ste n 0n the out: side, a cap provided with a threaded part engaging a corresponding threaded part on the body part of the cleanout, an opening through which the stern e extends, and the device adapted to receive a tool for removing the cover, all substantially as described.

2. In combination with the body part of the cleanout having the flaring cover seat, the cover with a beveled edge adapted to fit the part outside of the cover and bearing on its under surface upon the outer surface of the cover directly over the joint, and the guide.

projecting from the center of the cover through the cap, all substantially as described.

ROBERT GARVIE.
